I'm currently reading Real World Haskell ( http://book.realworldhaskell.org/read/), and it's an excellent book. It goes into detail on quite a few interesting and practical uses of the language. Also, in the spirit of this discussion, is there a resource that attempts to compare libraries for common tasks so developers can make informed decisions without having to research each library or approach on their own? As an example, in other languages you might read about CSV parsing from a few different sources and see a general consensus on how to approach it. After hours of digging through code on Hackage and reading up on different approaches, I can't seem to find a consensus in Haskell. If anyone knows of a book/resource that breaks down different approaches to common problems and when/why you might choose one over the other, I'm very interested. -Eric Rasmussen On Tue, Apr 26, 2011 at 3:52 PM, Edward Amsden wrote:

I am currently reading through Peyton-Jones "Haskell: The Craft of Functional Programming" (2nd ed.), as well as a great paper published by one of my professors (http://www.cse.chalmers.se/~rjmh/Papers/whyfp.html). However, what other works, in your opinions, should I look into to get a more complete understanding of functional programming?

You might consult the Typeclassopedia (Brent Yorgey).

Understanding these typeclasses helped me start understand the power of abstraction that Haskell (and FP in general) gives a programmer.

quoth the abstract: "The standard Haskell libraries feature a number of type classes with algebraic or category-theoretic underpinnings. Becoming a fluent Haskell hacker requires intimate familiarity with them all, yet acquiring this familiarity often involves combing through a mountain of tutorials, blog posts, mailing list archives, and IRC logs.

"The goal of this article is to serve as a starting point for the student of Haskell wishing to gain a firm grasp of its standard type classes. The essentials of each type class are introduced, with examples, commentary, and extensive references for further reading."

Thank you -- I will try your spreadsheet package for sure, and when I have more expertise in this area I'd be happy to contribute to the wiki. On Wed, Apr 27, 2011 at 3:00 AM, Henning Thielemann < schlepptop@henning-thielemann.de> wrote:

I think there won't be consensus in many cases, otherwise developers wouldn't have started to develop alternatives to existing packages. However if you did the work of comparing some libraries for the same purpose - how about writing a personal comparison in the HaskellWiki?

For the special case of CSV parsing I would of course recommend my spreadsheet package because it parses lazily. :-)

I think this book may have been mentioned before, "Functional programming: practice and theory" by MacLennan, Bruce J gives a fundamental idea of what it's all about. :) On Wed, Apr 27, 2011 at 4:28 AM, Christopher Svanefalk wrote:

First, thanks to everyone for your input! It is really appreciated, and I will be checking out the resources you provided.

Also, a correction: Haskell: The Craft of Functional Programming is written by Simon Thompson, not Peyton-Jones. Mixup on my part there :)
